A lightweight 400 Series OCLV Carbon frame with a road-smoothing IsoSpeed decoupler, a carbon fork, an 11-speed Shimano 105 road drivetrain, Tektro hydraulic disc brakes, hidden fender mounts, a Bontrager Montrose Comp saddle, and a lightweight Bontrager alloy wheelset with thru-axles for better responsiveness and control.

The fastest fitness bike. Period. A lightweight OCLV Carbon frame with IsoSpeed, carbon fork, and performance Shimano 105 drivetrain make FX Sport 6 the ideal ride for anyone who wants to ride ridiculously fast and crush fitness milestones.

FX Sport 6 is incredibly fast, and it has the added comfort and control of a flat handlebar
Fast is fun: FX Sport 6 is the quickest fitness bike on the road
You can pair FX with your smartphone and send your ride data to your favorite fitness app when you add DuoTrap S
It's easy to accessorize with fenders, lights, and more!
Like every Trek hybrid, it's backed by a lifetime warranty and supported by a wide network of retail partners

Discreet mounts accommodate full-coverage fenders for added utility.

Bontrager TLR (Tubeless Ready) Road is the first fully integrated tubeless system for road wheels. When you go tubeless with TLR, you can run lower tire pressure for increased traction and comfort without the threat of pinch flats.

Tough Bontrager Hard-Case tires help keep flats from slowing you down.

DuoTrap S integrates a Bluetooth®/ANT+ sensor into the frame. Log routes and track fitness progress on your computer or smart phone with no external sensor. Works with all major ANT+ wireless players, including Bontrager, Garmin, PowerTap, and SRM.

Bontrager stem technology lets you clip your gear directly to the stem for clean looks, maximum user friendliness.

Suspension for your hands. Our exclusive vibration-damping IsoZone material absorbs road bumps and buzz, giving you more control and an incredibly comfortable ride.

Hydraulic disc brakes offer the absolute strongest stopping power in all conditions, including wet and muddy.

At the core of Trek's endurance comfort technology is the IsoSpeed decoupler, the result of an 18-month study of how a racing bike performs over rough roads, and how that performance affects the rider.

We reserve the right to make changes to the product information contained on this site at any time without notice, including with respect to equipment, specifications, models, colors, and materials.

Bike and frame weights are based off Trek pre-production painted frames at time of publication. Weights may vary in final production.

The charts below show our recommended sizes based on height, but there are some other factors, like arm and leg length, that determine a great fit. That’s why you’ll see some overlap in our recommendations. Not every rider who’s 5´8˝, for example, will fit on the same size bike. The best way to find your perfect fit is to consult the experts at your local Trek retailer.
